The STX104 features an 8254 Counter/Timer chip providing three
counter/timers which can be used for frequency measurement, frequency
output, pulse width modulation, pulse width measurement, event count,
etc. The STX104 provides a register bank selection to bank select
between the 8254 Bank and the Indexed Register Array Bank; the Indexed
Register Array is not utilized by this driver, so the 8254 Bank is
selected unconditionally.

The devm_clk_register() is deprecated and devm_clk_hw_register() should be
used as a replacement.
Switching to the clk_hw interface also allows to use the built-in device
managed version of registering the clock provider. The non-clk_hw interface
does not have a device managed version.

According to the datasheet switching to a new channel function implies
multiple steps.
All functions must be selected for a minimum of 130 μs before changing
to another function.
The DAC_CODEx registers are not reset by changing channel functions.
Prior to changing channel functions, it is recommended to set the DAC
code to 0x0000 via the DAC_CODEx registers. Set the channel function
to high impedance via the CH_FUNC_SETUPx registers before transitioning
to the new channel function. After the new channel function is configured,
it is recommended to wait 150 μs before updating the DAC code.
Even though the channel switch is done at only at probe, where a device
reset is performed, that does not guarantee that the steps prior
changing to new channel function should be neglected.

Replace iio_device_register() with devm_iio_device_register() and remove
iio_device_unregister().
And st->reg is not used anymore, so remove it.
As Jonathan pointed out, couple of things that are wrong:
1) The device is powered down 'before' we unregister it with the
subsystem and as such userspace interfaces are still exposed which
probably won't do the right thing if the chip is powered down.
2) This isn't done in the error paths in probe.
To solve this problem, register a new callback adf4350_power_down()
with devm_add_action_or_reset(), to enable software power down in both
error and device detach path. So the remove function can be removed.
Remove spi_set_drvdata() from the probe function, since spi_get_drvdata()
is not used anymore.

Add filter bypass mode, which bypasses the low pass filter, high pass
filter and disables/unregister the clock rate notifier.
Currently a feature like bypassing the filter is not achievable
straightforward and not very deductive. The user has to look through the
code and call the set_lpf_3db_frequency and set_hpf_3db_frequency iio
attributes from the user interface using the corner cases (freq >
largest lpf supported by the part, respectively freq < smallest hpf
supported by the part). Moreover, in such case of bypassing the filter,
the input clock rate change might mess up things so we want to make sure
that it is disabled. Also, the feature will help emphasizing the filter
behavior, therefore adding it in the userspace will ease the
charcaterization of the filter's effects when active/disabled.
It was requested by users of the driver to ease the interaction with
different configuration modes of the device.

The ROHM BU27010 is an RGBC sensor with a flickering detection FIFO. The
RGBC+IR sensor functionality is largely similar to what the BU27008 has.
There are some notable things though:
- gain setting is once again new and exotic. Now, there is 6bit gain
setting where 4 of the bits are common to all channels and 2 bits
can be configured separately for each channel. The BU27010 has
similar "1X on other channels vs 2X on IR when selector is 0x0"
gain design as BU27008 had. So, we use same gain setting policy for
BU27010 as we did for BU27008 - driver sets same gain selector for all
channels but shows the gains separately for all channels so users
can (at least in theory) detect this 1X vs 2X madness...
- BU27010 has suffled all the control register bitfields to new
addresses and bit positions while still keeping the register naming
same.
- Some more power/reset control is added.
- FIFO for "flickering detection" is added.
The control register suffling made this slightly nasty. Still, it is
easier for maintenance perspective to add the BU27010 support in BU27008
driver because - even though the bit positions/addresses were changed -
most of the driver structure can be re-used. Writing own driver for
BU27010 would mean plenty of duplicate code albeit a tad more clarity.
The flickering FIFO is not supported by the driver.
Add BU27010 RGBC+IR support to rohm-bu27008 driver.

fwnode_irq_get[_byname]() were changed to not return 0 anymore. The
special error case where device-tree based IRQ mapping fails can't no
longer be reliably detected from this return value. This yields a
functional change in the driver where the mapping failure is treated as
an error.
The mapping failure can occur for example when the device-tree IRQ
information translation call-back(s) (xlate) fail, IRQ domain is not
found, IRQ type conflicts, etc. In most cases this indicates an error in
the device-tree and special handling is not really required.
One more thing to note is that ACPI APIs do not return zero for any
failures so this special handling did only apply on device-tree based
systems.
Drop the special handling for DT mapping failures as these can no longer
be separated from other errors at driver side. Change all failures in
IRQ getting to be handled by continuing without the events instead of
aborting the probe upon certain errors.

There are devices (such as Murata IRS-D200 PIR proximity sensor) that
check the data signal with a running period. I.e. for a specified time,
they count the number of conditions that have occurred, and then signal
if that is more than a specified amount.
`IIO_EV_INFO_PERIOD` resets when the condition no longer is true and is
therefore not suitable for these devices. Add a new `iio_event_info`
`IIO_EV_INFO_RUNNING_PERIOD` that can be used as a running period. Also

Commit 813665564b ("iio: core: Convert to use firmware node handle
instead of OF node") switched the kind of nodes to use for label
retrieval in device registration. Probably an unwanted change in that
commit was that if the device has no parent then NULL pointer is
accessed. This is what happens in the stock IIO dummy driver when a
new entry is created in configfs:
# mkdir /sys/kernel/config/iio/devices/dummy/foo
BUG: kernel NULL pointer dereference, address: ...
...
Call Trace:
__iio_device_register
iio_dummy_probe
Since there seems to be no reason to make a parent device of an IIO
dummy device mandatory, let’s prevent the invalid memory access in
__iio_device_register when the parent device is NULL. With this
change, the IIO dummy driver works fine with configfs.

The affected lines were resulting in a NULL pointer dereference on our
platform because the device tree contained the following list of
compatible strings:
power-sensor@40 {
compatible = "ti,ina232", "ti,ina231";
...

Since the driver doesn't declare a compatible string "ti,ina232", the OF
matching succeeds on "ti,ina231". But the I2C device ID info is
populated via the first compatible string, cf. modalias population in
of_i2c_get_board_info(). Since there is no "ina232" entry in the legacy
I2C device ID table either, the struct i2c_device_id *id pointer in the

Fix this by using the already populated type variable instead, which

The code uses a local variable to initialize a null pointer in order to
avoid accessing this null pointer later on.
Simply removed the 'unused' variable and check for the null pointer just
before accessing it.

The current implementation returns the error code as part of the

This can lead to returning an incorrect positive value in case of

In order to avoid this case, be more strict in error checking.

Here are a small set of changes for 6.5-rc1 for some driver core
changes. Included in here are:
- device property cleanups to make it easier to write "agnostic"
drivers when regards to the firmware layer underneath them (DT vs.
ACPI)
- debugfs documentation updates
- devres additions
- sysfs documentation and changes to handle empty directory creation
logic better
- tiny kernfs optimizations
- other tiny changes
All of these have been in linux-next for a while with no reported

According to the datasheets of supported meson SoCs length of ADC_CLK_DIV
field is 6-bit. Although all supported SoCs have the register
with that field documented later SoCs use external clock rather than
ADC internal clock so this patch affects only meson8 family (S8* SoCs).
